We are not sure how or why the began, but we have a good understanding of events a fraction of a second later, namely, a which released , and clouds of .

New stars, such as the , formed from these materials in the of the Galaxy. The dust and molecules formed such as .
appeared on Earth (we are not sure how) and soon evolved into (germs). The of life was played out upon the moving stage formed by .
Single cells with a appeared and plants such as and animals such as evolved. These single cells began to live together in to form more complex algae and animals.
such as appeared about the same time as the plants began to , rapidly . Later types of vertebrates (called ) evolved to live out of water and dominated the land for millions of years.
Plants, insects and vertebrates evolved into , and all at about the same time.
appeared very recently and rapidly dominated and , also learning how to leave it. There are vast resources in our Solar System and huge amounts of energy. Once humanity learns to capture these resources we will become wealthy beyond our wildest dreams.
People have also created , and software is now being developed which can learn and evolve. If computers ever learn how to develop other computers, they might become completely independent of their human inventors. Independent computers might rapidly colonize this corner of the Galaxy. But we are so far away from even then next nearest galaxy that it is unlikely that people or computers will ever spread very far into the Universe.
The Sun will eventually , but by that time organic life will probably be largely irrelevant.
